1. In the design of an experiment we have a treatment T with four levels T1,T2, T3, T4. We are planning to use CRD model and we have only n -20 observations available How should we allocate the n observations to the four treatments to minimize the average variance of the estimated treatment eftects AV (var(i) + var(T2) + var(T3) + var(T4)) 4 Hint: Find the values of ri by minimizing Ay subject to the constraint Σに1 , nj

Gj, Г, 2, 3, 4:3 How should we allocate the n observations to the four treatments to minimize the average variance of the estimated treatment effects AV = 슷 (var(T1) + var(T2) + var(fs) + var(T4)) UaT T4 Hint: Find the values of r, by minimizing AV subject to...
An experiment to investigate the effects of various dietary starch levels on milk production was conducted on four cows. The four diets, T1, T2, T3, and T4, (in order of increasing starch equivalent),...
An experiment to investigate the effects of various dietary
starch levels on milk production was conducted on four cows. The
four diets, T1, T2, T3, and T4, (in order of increasing starch
equivalent), were fed for three weeks to each cow and the total
yield of milk in the third week of each period was recorded (i.e.
third week to minimize carry-over effects due to the use of
treatments administered in a previous period). That is, the trial
lasted 12...

2. (a) Let us consider a full model of a balanced (all t treatments have equal number of observations r) CRD design with t treatments and r replications of each treatment, hence having n-rt observations i. Minimizing sum of square error Δfull(μ, Tỉ)-Σι-12jai (Vij-l-ri)2 with respect to μ and Ti find the least square estimators of μ and Te as μ and Ti Hint: Take derivative of the objective function with respect to u and Ti and equate then to...

Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...
